Multibeam data acquired with Okeanos Explorer’s EM302 multibeam system is overlaid on top of satellite-altimetry data. As you can see in this image, bathymetric data created with the ship’s EM302 multibeam is much more detailed, allowing us to define previously unknown or poorly known features, gaining a more accurate and precise picture of the character and nature of the seafloor. Image created in Fledermaus version 7 using data acquired during cruise EX0909 offshore Hawaii’s big island (Wini Seamount). Image courtesy of NOAA Okeanos Explorer Program.
